1. Whilst SAS can be run on win98, I'm not sure if all of the features work in win98. I also don't know if the rootkit detections do the same as avast or if SAS is just scanning for known rootkit files used to install a rootkit.
I also don't know who effective a rootkit might be in playing on a win98 system.
2. The scans in SAS (legit is perhaps the wrong word) have generally been fine for me but I do know my way around a bit in these matters. You should get out of the habit of swearing, 'delete' you never delete always quarantine and investigate and never delete until you are absolutely sure it is malware.
There are things like tracking cookies that scare the living daylights out of people as they make a big deal about them when they really aren't. They are more of a privacy issue rather than a security issue and in the Preferences, Scanning Control I disable them and a number of other options (outside of the default settings), see image. I don't know if some of the options would be different with win98.
It knocks spots of adaware for sure and much better than S&B IMHO.
3. If they didn't play well together, you wouldn't see it in my signature
I suggest a visit to http://www.superantispyware.com/WebHelp/SUPERAntiSpyware.htm for some light reading.
I took a quick scan of the Info. I'll read it in more detail a bit later. But, in my brief preliminary speed read, I didn't really see any indications that something would NOT work on Windows 98SE. I did see the differences between the FREE version and the Professional version, but I believe those differences were differences that would affect all versions of Windows if one downloaded the FREE version ... NOT just Windows 98SE. Like some of the differences are No Registry Check in the FREE version and No Real-Time Scanning in the FREE version, among various other differences. Well, that No Real-Time Scanning would actually sorta be what I wanted ... since I didn't want to risk it slowing down my system by running in the background.
So yeah, I'll read up more on it and who knows? By this coming weekend, I'm bound to have it installed in my system.
As for your recommendation of thinking more in terms of "Quarantine" instead of "Delete?" Actually, no argument there. Back when I used to use McAfee, whenever McAfee gave me the option of "Cleaning" or "Repairing," I much rather preferred that. It was only when those didn't work or they weren't an option, that I resorted to Delete.
But, Okay, I'll have to admit that on someone else's computer on which I did a lot of Tweaking & Maintenance a week ago ... after I uninstalled NOD32 AND AOL Safety & Security Center and Installed avast! ... avast! found 4 Win32:Virus Trojan-gen or something like that. As I type this, those 4 Malware elements are still in the Virus Chest. My original plan was to wait a week and if nothing was malfunctioning on the computer, I was going to delete those 4 Infected Files. Now after reading stuff on this forum, I guess I'm going to change my plan to checking those 4 Infected Files on VirusScan Jotti and VirusTotal to see if they're not False Positives.
I'm gonna have to do the same with these 2
AIM Files that
ALWAYS get tagged by avast! on MY computer as being
Adware-Gen. The way I see it, that cannot be possible. I've done immediate avast! Manual Scans straight fresh off of Total Windows Reinstalls ... and those SAME 2 AIM Files always get tagged by avast! Those Files just came off of the AOL Installation CD, so they cannot possibly be
Infected. Unless they ARE technically Adware-Gen even though they come straight off of the AOL Installation CD.
Thanks again for your input / info / advice, David. I'm finding a lot of good stuff here in this forum
